So if both hips are scored the total that dog achieves will be between a TOTAL of 0 and 106 2 x 53. This should result in gradual improvement in the breed over time.
Yet even if both parents have great hips this is not a guarantee that the puppy will be free from hip.
How much to hip score a labrador. The maximum score for most of these is six 6. The maximum score for each hip is 53. The maximum score for the dog is 106 ie.
The ANKC breed average of hip. At the time of writing the BMS for Labradors is 12 This is the total for the two hips added together. You can check the latest data on the British Veterinary Association website.
A balanced score of 12 would be 66 a better score would be 33 and a perfect score would be 00. Outside of the UK scoring systems are different. This means that a perfect hip will score 0 and the worst possible hip will score 53.
Of course you have to remember that a dog just like us has two hips so a perfect pair would be written down as 00 and the worst possible as 5353 The right hip is always the first figure and the left hip the second. The guidelines on hip score for parents of Labrador puppies seems to be a total of 6 with equal numbers. I have two questions.
1 if either parent has a score of 45 total 9 I should delete these form my theoretical wish list. Or in practice is this as good as it. From statistics gained in 2005 for various dog breeds it was found that the average Labrador hip score was 12 which compared favourably with breeds such as the Newfoundland which recorded a score of 21 and the Bull Mastiff which registered at 23.
The scores dont look right the breed mean score for Labradors is 108 which is the score of both hips added together ideally parents should be below this mean score you do see the scoring stated with the score of both hips and with say a total score of 10 it may be expressed as 55 or 46 for example. The way those are expressed that means one hip is a 4 and one hip a 32 in the dam and 45 in the. Nine features of each hip are scored according to the degree of dysplasia observed 0 no signs and scores from each feature are summed to give a total from 053 for each hip and 0106 in total.
Although voluntary the rate of participation in the UK is good. For example 810 of all annually registered Labrador Retrievers the most popular breed in the UK with between 33 398 registrations in 1999 and 45779 registrations in 2005 are scored. These test rank the hips as Excellent Good and Fair.
You should not buy a puppy without ensuring the parents have at least a Fair rating and preferably a Good or Excellent hip score. The OFA also has the hips scores for Hip Dysplasia. Borderline Mild Moderate and Severe.
Obviously dogs exhibiting these scores should not be bred. Yet even if both parents have great hips this is not a guarantee that the puppy will be free from hip. They are often given as a 26 type number but a breeder will take the total given so 8 in this case to calculate whether the dog is sound for breeding.
Scores are from 0 - 53 with 53 being the worst per hip so the worst possible combined score is 106. Genetic evaluation of hip score in UK Labrador Retrievers. Lewis TW1 Blott SC Woolliams JA.

The best result is 00 which means there are no changes at all to the joints and the worst possible score is 5353 which means the dogs hips are very badly made and degenerative joint disease in the form of arthritis will set in very early in the life of the dog and will eventually probably overwhelm the individual.
SCORE OF 2 - the CrAE is flattened throughout most or all of its length and there is usually both medial and lateral joint space divergence. SCORE OF 3 - higher scores are given when there is positive evidence of abnormal wear andor remodelling of the edge. Early change is manifested by slight bilabiation which shows as cranial curvature of a small outer segment of the CrAE.
The median for Labradors. A hip score will usually be expressed as two numbers with a in between. That gives you the score for each hip.
For example 45 means one hip was 4 the other was 5 giving a total of the median 9. Its not just about meeting the average though. Preferably the hips are both roughly the same score.
45 is more desirable than 09 for example. The minimum score for each hip is 0 and the maximum is 53 giving a range for the total score of 0 to 106. This total score should be compared to the breed median.
If the dog is registered with the UK Kennel Club their results will be sent to the Kennel Club for publication on the Kennel Club website. They will score this x-ray with each hip of the two hips scoring between 0 lowest and 53 highest. So if both hips are scored the total that dog achieves will be between a TOTAL of 0 and 106 2 x 53.
Currently the breed average for a total of both hips sits at around 16. So dogs around or under this score have average or better than average hips to give a guide. The score can also be shown.
Most Labrador breeders should be aiming to breed from stock with a hip score that is lower than average and balanced. This should result in gradual improvement in the breed over time. A good hip score for a Labrador is probably anything under 6 made.
Currently the breed average for a total of both hips sits at around 125 for Labradors. So dogs around or under this score have average or better than average hips to give a guide. The score can also be shown sometimes as two numbers left hipright hip - so something like 54 total of 9 - good or maybe 3321 total of 54 - poor.
In the first ten years of the scheme the average hip score of UK Labradors went down from 165 1996 to 128 2007. OK thats hips what about elbow dysplasia. Elbow dysplasia is a much more complex condition comprising a number of different problems but once again it is a genetic developmental condition that seems to be becoming more common possibly as a result of inbreeding.
The degree to which a dog is affected by hip dysplasia is represented by a score given to each hip. This score ranges from 0 to 106 0 to 53 for each hip with a score of 0 representing the least degree of hip dysplasia and 53 representing the most.
